The roof is a continuum of the walls, so to clad the walls, I had to also clad the roof. Sticking the silver insulation was somewhat exhausting as it is all upside down work. I used a container of glue (or more) for each section.
The other exciting thing about the the roof is that it has the biggest hole of the lot to cut for the roof window. The vibrations and noise were exciting again as I cut this foot square hole. It was into fibreglass this time and so I could use different and marginally easier jigsaw blades. Having cut a rough hole, I sanded down the sides to get to the right size and this was a good method as it meant that I avoided any nasty chips in the roof. But it took an age.
Then I made a couple of little wooden pieces the same shape as the dip in the roof and added fiberglass to make up the lower section. By the time this had dried and been sanded down and a lick of paint, it was already getting to the end of the daylight. So overnight, the window is just sitting on the roof with a hope of a dry, calm night.
In fact it sat there for the next few weeks (although I taped it down) as there was lots of work to get to the point where I could fit the cladding and hence properly fit the vent. The problem was that the piece of cladding stretched over into the second section of roof and this section had the loo vent in the other side and hence could not be insulated until that vent had been fitted and it took ages to arrive. The temporary fit worked OK until frost got under the tape and then it leaked, but only for a couple of days before the job was completed.
Next step was to fit endless battens around the curves, between the van roof supports and then the plywood cladding. It was VERY difficult to bend the 4mm plywood sheets around the curve at the junction of roof and walls. The sheets were too big to heat across the entire width at the same time and the curve too sharp. I scored the back, but they still didn't bend nicely in a curve. Adequate, but not perfect I reckon.
